Chemical purification services for off-spec chemical recovery

Certified chemical purification for off-spec chemicals

AQ MarTest provides professional chemical purification services for contaminated and off-spec chemical products across global industrial operations. Treatment is performed directly at terminals, chemical plants and storage facilities using certified mobile filtration systems.

Chemical purification helps restore valuable products without unnecessary disposal or replacement. By treating chemicals on-site, AQ MarTest reduces operational downtime, avoids transport risks and supports sustainable product recovery.

This is especially critical for high-value bulk chemicals where contamination can create significant commercial exposure.

Common chemical contamination challenges

Chemical products can become off specification due to:

  • water contamination
  • chlorides
  • dissolved iron
  • peroxides
  • carbonyls
  • particulate contamination
  • oxidation
  • color deviations
  • odor deviations
  • failed appearance standards

These issues often delay transfer, blending or final delivery and may trigger contractual or insurance complications.

Chemical purification restores specification before larger operational losses occur.

Chemical purification technologies

AQ MarTest uses several purification methods depending on the chemical composition and contamination type.

Chemical Filtration

Chemical filtration uses high-performance adsorbent media to remove dissolved contamination such as chlorides, peroxides, carbonyls, dissolved iron and water.

This process is essential for restoring sensitive chemical parameters and improving product stability.

Mechanical Filtration

Mechanical filtration removes visible and microscopic particles from liquid bulk chemicals and supports appearance improvement and cleanliness restoration.

Magnetic Filtration

Magnetic filtration captures ultra-fine metallic contamination that traditional particle filtration cannot fully remove.

This is particularly valuable for sensitive chemical products.

Chemicals commonly treated

AQ MarTest routinely performs chemical purification for:

  • methanol
  • ethanol
  • benzene
  • xylene
  • toluene
  • styrene monomer
  • MEG
  • caustic soda
  • phosphoric acid
  • paraffins
  • specialty chemicals

Each project is based on laboratory analysis and technical validation before field execution begins.

Restoring critical product specifications

Chemical purification improves:

  • appearance
  • color
  • odor
  • acidity
  • water content
  • flash point
  • total contamination
  • ISO cleanliness
  • haze rate
  • dissolved contaminant levels

The goal is full recovery to commercial specification wherever technically possible.

AQ MarTest laboratories support this process with treatment feasibility testing and filtration trials.

Certified chemical purification worldwide

All chemical purification projects are executed under ISO 9001, ISO 14001, ISO 45001 and VCA-P certified systems. This ensures safe handling and full compliance with petrochemical industry standards.

AQ MarTest combines certified equipment, laboratory expertise and global field operations into one complete chemical purification service.

When valuable chemicals move off specification, rapid and controlled recovery is essential.
